摘要
动态压井法是一种较适用于海洋深水井控的方法,在一定范围内得到了应用。根据动态压井原理,建立了通过钻柱注入压井液的动态压井模型,得出了一种较合理的压井参数计算方法,包括初始压井液及加重压井液的密度和最大最小流量的计算,并通过实例验证。
It is indicated from practices that dynamically killing well is one way suitable for a well control during deepwater drilling. And it has been applied to some domains. In this study, a dynamically killing well model which is injected into killing fluid by drill string is established; and a method to reasonably calculate parameters of killing well, such as density and (maximum and minimum) flow rate of primary and kill-weight drilling fluid, is obtained. It is illustrated from case study that a better result was achieved from a blowout when directional and highly migrated wells were controlled by dynamically killing well.
